I have a dual-monitor, ati setup on gnome-shell that was just fine until this morning.

Then, this happened.

Look closer...

Whatever has happened to my ubuntu setup? My second monitor still works, entirely normally, with the exception that I cannot (obviously) access activities (as i am in gnome-fallback ). I do wish to resume my work...

EDIT: By entirely normally, I mean I can move my mouse over it and have seperate windows on it and stuff. It's not mirroring.
